Plant erect to spreading, glabrous. Internodes slightly angular when young, terete when older. Leaves elliptic, obtuse to rounded with a small blunt mucro; lamina 5-8 cm long, 2-4.5 cm wide, finely recurved at margin, dull both sides or slightly lustrous on adaxial surface, attenuate at base into distinct petiole 6-15 mm long; venation distinct on abaxial surface. Inflorescence axis usually 8-13 (rarely to 30) mm long, with usually 1 (rarely 2 or 3) pairs of triads sessile or on peduncles to 1 mm long; all flowers sessile; bracts 1.5-2 mm long, rounded. Calyx 0.7 mm long, irregularly split. Corolla in mature bud slender, 23-30 mm long, red below, green above; petals united in lower 2 mm. Anthers 3 mm long, slightly shorter than free part of filament. Fruit ovoid, 9 mm long.
